Unable to install PyNIO and PyNGL in Debian Linux

[NJUlsg]

Hi, I try to install pynio and pyngl in Debian Linux (running in a virtual machine) by using "conda create --name pyn_env --channel conda-forge pynio pyngl", but it failed.

These are details:

• Virtual machine version: VMware® Workstation 14 Pro 14.1.2 build-8497320
• Operating system: Windows 10, 64-bit (Build 17134) 10.0.17134
• Debian version: Linux debian 4.9.0-7-amd64 lbLineLabelStrings #1 SMP Debian 4.9.110-3+deb9u1 (2018-08-03) x86_64 GNU/Linux
• Enter commands at the console:

shigan@debian:~$ conda create --name pyn_env --channel conda-forge pynio pyngl
